Embodiment Construction

[0113] Next, the construction method of the pressure pipe using the one-step three-stage fastening device of the pressure pipe connection pipe joint of the present invention will be specifically described with reference to the accompanying drawings.

[0114] The construction method of the pressure pipe using the one-step three-stage fastening device of the pressure pipe connection pipe joint is characterized in that it includes the following steps: (a) in order to install the pressure pipe 50, excavate the ground in the open air, but it is different from the existing There is a difference in technology, without excavating additional operating space, excavating underground along the length direction of the pressure pipe 50 so that it has the minimum space where the pressure pipe 50 can be arranged;

[0115] (b) Taking the pressure tube insertion tight fitting part A as the base point, the fastener inserting tight fitting part B and the watertight rubber are sequentially formed w...

Abstract

The present invention relates to a one-step three-stage fastening device for a pipe joint for pressure pipe connection and a construction method for a pressure pipe using the fastening device. In particular, the device is characterized in that the device has a one-step connection structure. An organic fastening structure is formed inside the pipe joint for pressure pipe connection, whereby the joint is completed and fixed by only one operation of inserting the pressure pipe into the pipe joint for pressure pipe connection, wherein the organic fastening structure is formed in the It is composed of the 'fixed structure' of the pressure pipe insertion - tight fitting part A and sleeve insertion - tight fitting part D, the 'double frictional resistance structure' based on the fastener 20, and the 'watertight structure' based on the watertight rubber pad. The present invention adopts a one-step method, so the jointing and fixing operation is easy, the efficiency of the connecting operation is high, and the construction period is shortened. In addition, the present invention does not require the operator to personally perform the connecting operation, and does not require additional operation and excavation space, so the excavation operation is efficient. And affordable.

Description

technical field [0001] The present invention relates to a one-step three-stage fastening device for a pipe joint for pressure pipe connection and a construction method for a pressure pipe using the fastening device. In particular, the device is characterized in that the device has a one-step fastening structure, That is, an organic fastening structure is formed inside the pipe joint for pressure pipe connection, so that the joint is completed and fixed by only one operation of inserting the pressure pipe into the pipe joint for pressure pipe connection, wherein the organic fastening structure It is composed of the 'fixed structure' formed on the pressure pipe insertion-adherence part A and the casing insertion-adhesion part D, the 'double friction resistance structure' based on the fastener 20, and the 'watertight structure' based on the watertight rubber pad. [0002] The present invention adopts a one-step method, so the connection and fixing operation is easy, so that not o...
